In a statement issued by SAWS on Sunday March 10, the system has drifted slowly around the eastern and southern parts of the Mozambican Channel, causing heavy thundery downpours over the eastern coastline of Madagascar.

“Thus far, surface winds in association with the system have not been particularly strong or damaging. In the days ahead, however, the system is expected to begin deepening and intensifying, as early as this evening. At this stage, the primary regions at risk are the southern coastal regions of Mozambique, southwards of Beira,” SAWS said.

According to SAWS, the system was positioned at approximately 20.1 South 39.9 East.

“The central pressure in association with the system is still above 1 000hPa, currently estimated to be 1 005hPa, and it is moving due west at approximately 11 knots (20km/h). While there is still significant uncertainty among Numeric Weather Prediction models regarding the intensity and future movement of the system, there is broad agreement, at least in the short term (covering the next one to two days) that the system will continue moving towards the central Mozambican coastline, while undergoing a steady but gradual intensification. In the opinion of the Regional Specialised Meteorological Centre [RSMC] at La Reunion (the official source of guidance for tropical systems in the southwest Indian Ocean region), the system may intensify sufficiently to attain Moderate Tropical Storm status (with sustained winds of 63 to 80km/h) as early as this evening,” SAWS said in the statement.

The current predicted track for this system, prepared by RSMC La Reunion, is provided below.

According to SAWS, the curved, parabolic track suggests that the system is likely to be overland, over southern Mozambique during Tuesday, then exiting southern Mozambique near Xai-Xai on Wednesday.

“While the eastern parts of South Africa are not expected to be directly affected by this system, the Lowveld regions of Mpumalanga and Limpopo, as well as northern KwaZulu-Natal, could experience a spell of windy, rainy weather in the period between Tuesday and Thursday this week. Further details in this regard will be provided by the SAWS in subsequent follow-up media releases. SAWS will continue to monitor any further developments relating to this weather system and will issue subsequent updates as required. Furthermore, the public is urged and encouraged to regularly follow weather forecasts on television and radio.
